Rice Water Weevil Lissorhoptrus oryzophilus Kuschel

Abstract

The rice water weevil, Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae), native to North America, is one of the most destructive insect pests of rice in the US and eastern Asia. It was introduced into China in the 1980s and so far has spread widely throughout the country. Much work has been done with respect to its ecology and control methods. Here, we review the invasion history, mechanisms underlying its invasions and rapid spread, and major control methods in China. We also discuss factors responsible for its wide spread in China. In addition, we report on options employed to control this weevil. Finally, we propose future directions for research, particularly on the ecology and the development of a more comprehensive control strategy for this weevil in China.
